Moving from generalisations to specificity about mangrove-saltmarsh dynamics
Spatial and temporal variability in factors influencing mangrove establishment and survival affects the distribution of mangrove, particularly near their latitudinal limit, where mangrove expansion into saltmarsh is conspicuous. In this paper the spatial variability in mangrove distribution and variability in factors influencing mangrove...
Rogers, Kerrylee; Krauss, Ken W. Airborne bacteria in Earth’s lower stratosphere resemble taxa detected in the troposphere: results from a new NASA aircraft bioaerosol collector (ABC)
Airborne microorganisms in the upper troposphere and lower stratosphere remain elusive due to a lack of reliable sample collection systems. To address this problem, we designed, installed, and flight-validated a novel Aircraft Bioaerosol Collector (ABC) for NASA’s C-20A that can make collections for microbiological research investigations up to...

Detecting and quantifying environmental thresholds is frequently an important step in understanding ecological responses to environmental stressors. We discuss two statistical issues often encountered in threshold detection and quantification when statistical null hypothesis testing is used as a main analytical tool.The hidden multiple-comparison...
Qian, Song S.; Cuffney, Thomas F. State-space models to infer movements and behavior of fish detected in a spatial array of acoustic receivers
We developed state-space models for inferring movements and behaviors of fish implanted with acoustic transmitters and detected within a spatial array of stationary acoustic receivers. In these models fish movements and behavior switching are specified using a hidden Markov model of the changes in an individual's latent activity center. The...
Price, Melissa E.; Dorazio, Robert Sturgeon in the Sacramento-San Joaquin watershed: new insights to support conservation and management
The goal of a day-long symposium on March 3, 2015, Sturgeon in the Sacramento–San Joaquin Watershed: New Insights to Support Conservation and Management, was to present new information about the physiology, behavior, and ecology of the green (Acipenser medirostris) and white sturgeon (Acipenser transmontanus) to help guide enhanced management and...

Water use in Louisiana, 2015
In 2015, approximately 8,720 million gallons per day (Mgal/d) of water was withdrawn from groundwater and surface-water sources in Louisiana, a 2.6 percent increase from 2010. Total groundwater withdrawals were about 1,750 Mgal/d, an increase of 12 percent from 2010, and total surface-water withdrawals were about 6,970 Mgal/d, an increase of 0.44...

Roosenburg, Willem M.; Kennedy, Victor S.; Lovich, Jeffrey E.; Hart, Kristen How do upwelling and El Niño impact coral reef growth? A guided, inquiry-based lesson
This lesson uses real-world data to guide students toward understanding how climate and ocean variables impact coral reef growth. To begin this activity, students hypothesize how changes in environmental conditions could affect coral reef growth. They then compare metrics for reef growth (linear growth and percent coral cover) between two reefs in...
Gravinese, Philip M.; Toth, Lauren T.; Randall, Carly J.; Aronson, Richard B. Basin-scale model for predicting marsh edge erosion
Recent attempts to relate marsh edge retreat rate to wave power have met varying levels of success. Schwimmer (2001) correlated wave power to marsh boundary retreat rates over a five-year period along sites within Rehoboth Bay, Delaware, USA. Marani et al. (2011) derived a linear relationship between volumetric retreat rate and mean wave power...
Jafari, Navid H.; Chen, Qin J.; Couvillion, Brady; Johnson, Cody L.; Everett, Thomas Landscape conservation design for enhancing the adaptive capacity of coastal wetlands in the face of sea-level rise and coastal development
Coastal wetlands provide many valuable benefits to people and wildlife, including critical habitat, improved water quality, reduced flooding impacts, and protected coastlines. However, in the 21st century, accelerated sea-level rise and coastal development are expected to greatly alter coastal landscapes across the globe. The future of coastal...
Osland, Michael J.; Borchert, Sinead; Enwright, Nicholas Hyperspectral remote sensing of wetland vegetation
Chapter 11 by Ramsey and Rangoonwala provides an overview of how hyperspectral imaging (HSI) advances the mapping of coastal wetlands that comprise a unique variety of plant species, forms, and associations. Each description begins by seeking to uncover the relationship between canopy hyperspectral reflectance and one or more of the aggregated...
Ramsey, Elijah; Rangoonwala, Amina Updated statewide abundance estimates for the Florida manatee
Knowing how many manatees live in Florida is critical for conservation and management of this threatened species. Martin et al. (2015) flew aerial surveys in 2011–2012 and estimated abundance in those years using advanced techniques that incorporated multiple data sources. We flew additional aerial surveys in 2015–2016 to count manatees and again...
